No Wi - Fi after installing Windows 7

Hello!

I just installed Windows 7 Ultimate on my laptop Lenovo B5400. I used Windows 8.1 and it was working fine, but now there is no Wi - fi. I read many forums about this, I have donwloaded the latest version of the wifi Lenovo driver and still nothing appears... If I plug the cable. At home it would be OK, but soon I'll leave abroad and I have ethernet, wifi only cable.

Help, please.

You must install the driver after you download.

You will have to perhaps download and install Lenovo energy management driver.

You must also press the right combination to activate the adapter wireless keys Fn and Fx.  It is usually Fn + F5, but it might be Fn + F4, or it could be a physical switch.

For more information about the above two points, see https://support.lenovo.com/us/en/documents/ht072689

Click the start ORB, type device manager in the start search box and press ENTER.

What devices are listed under 'network adapters '?

Double-click any device that displays a warning icon and make the text in the box under "device status".

  • SD card is not working properly after installing windows 10

    I have a MacBook Pro (retina, 13 inches, early 2015) with EL Capitan 10.11.5 and after I installed 10 windows using bootcamp, everything worked fine at first, but after I deleted my part of windows and then installed windows 10 the second time, the SD card is not working properly. She mounts only if the computer shuts down first, and then start. If I take the laptop directly, the SD card will not rise. The same thing happens when I switch systems using a control option key or bootcamp Center where when I switched to another system, the SD card that was mounted on the old system does not appear in the new system. I was trying to solve this problem remove the part of windows before you reinstall it again once, so I found that after I deleted the windows part, the problem is gone and it reappeared after installing windows 10 even once. I also found that after I installed windows the total volume of hard drive (128g front) became 121g.

    Hello LorinMax,

    Thanks for this info and choosing the communities Support from Apple. I know the importance of your work with your Macbook Pro SD card!

    If I understand correctly, you cannot use your SD card, unless you stop and then restart. Because this behavior started when you installed Boot Camp, I would start with the following steps:

    1. first of all, start by repairing your hard disk in disk utility to correct the unexpected problems that could be the cause of this behavior.

    Disk utility (El Capitan): a disc repair

    2. use Mode without fail to start up your Mac so that it performs certain checks, remove files from the system cache, check your startup disk and trying to fix problems if necessary directory.

    Try safe mode if your Mac does not end commissioning

    Graphics performance limited in recovery of OS X or in safe mode

    3. According to Boot Camp Installation & Setup Guide, you may need to back up your personal data and reinstalling OS X, then reinstall Windows via Boot Camp and related support files.

  • Computer OS used to start after installing windows 10

    Hello im having problem starting my system after installing windows 10. I did the install and it worked fine since the upgrade to 8.1. But then I tried to format the drive and in the menu format, he's stuck at 2%, and then I restarted the computer. Now it will hang at the hp logo and go back to the same logo. Do I have to replace my hard drive?

    What I understand, if you have completed the 10 Windows Installer and everything has happened until the end, then you are supposed to be able to do a clean install with the download of Windows 10 DVD or USB.  With a working computer, GO to THIS PAGEand scroll down to the button "download tool" selection the 64-bit version.  Once clicked, it will ask you if you want a DVD or USB for the iso.

    Once it's done and you have the DVD or the USB version, see if you can install Windows 10.  If this fails, you may need to replace the hard drive.

    Micro is a part of webcam so be sure that driver webcam is properly installed and driver sound, you need to as well.

    After that, check the sound settings. Make sure that the Microphone is enabled and test it again with amp active microphone.

  • HP Officejet 7612: analysis of problems after installing Windows 10

    After installing Windows (prior to Windows Vista) 10, scan documents with my HP Officejet 7612 became a hell of a job.

    Printing is no problem.

    With Webscan, I can only scan and save 1 page at a time, I can not scan several pages of the document 1 more.

    I downloaded "Extended Scan" but when I try to use this app, it says "year error occurred while scanning" without more information.

    With "HP Scan and capture" I can't scan the size of A3 paper full of documents and there seems to be no possibility to change the size of a3 paper. Maximum size is 'legal letter '.

    Same problem with "Windows Fax and scan."

    Are there other ways to recover the possibilities of full scan from my HP Officejet 7612?

    My pc runs Windows XP Home Media edition.  I installed Windows Service Pack 3 successfully, or so I thought. Whenever I turn on my pc a box opens indicating "files which are required for Windows to run properly have been replaced by unrecognized versions."  To maintain the stability of the system.  Windows must restore the original versions of these files.  Install your Windows XP Professional CD2.  I don't have any Windows XP Professional CD that I use the Home Media Edition. If I press Cancel repeatedly, the window disappears to return with the same information, but ask me to install Windows XP Professional CD3.  How can I stop this happening?

    The whole office is there, but it is located in the Center, if the screen, with black bands at the top and bottom. By clicking full screen on the top right has no effect.

    Hi Jeremy,.

    Thanks a lot for your help. You're right, I should have said no upgrades and updates.
    There were a total of 10 updates:
    4 a security updates for Vista,
    1 security update for the Microsoft 2010 information access path,
    1 day of cumulative security for IE9.
    1 windows Live essential 2011
    1 definition update Windows Defender (KB915597)
    1 "" for Office 2010 "
    1 April 2013 malware tool
    I uninstalled Windows Live Essentials. I felt that I should not uninstall the updates of security, and the Defender update can not be uninstalled. It made no difference.
    I also checked the graphics card and told me that I had the latest version of the software.
    Then I checked the configuration of the monitor and graphics card configuration and found I could set the configuration to full frame. I did it and now all is well again.
    How and why the full frame disappeared April 16 remains a mystery.
    Thank you very much for your information without your help I would have been unable to delve deeply into the system. I learned a lot.

  • Does not fingerprint after installing Windows 7

    I bought 3 items of T500 with installed Windows 7 Home. With this OS footprint scaner worked properly.

    After installing Windows 7 Professinal, fingerprint reader does not work. All instaled divers. There is no error in DeviceManager. But when I run the software of fingerprints, it is said that scanner is not lit.

    Make sure that the installed driver is actually the one that came with the Lenovo Fingerprint Software and not the one that you got from Windows Update. I've seen similar problems several times where Windows 7 is installed and get fingerprints from windows update driver/software and the software Lenovo to fingerprints do not work because some parts of the software, I got from windowsupdate is left on the computer.

    Which version of the driver of the fingerprint reading is installed on your computer?

    You can try uninstalling Lenovo Fingerprint Software and restart. Then, after the reboot if there is still a driver installed for the fingerprint reader in Device Manager, right click and select uninstall and also check the box that says to delete the driver. You may have to restart again. If you had several drivers fingerprint installed you may need to repeat this step twice. So when Device Manager shows the fingerprint with no check reader driver installed if you have any software fingerprint authentec or authentec truesuite installed under "uninstall or change a program". If you find any uninstall and restart. If you can successfully eliminate all the reader of fingerprints in the device should be listed in Control Panel with no driver installed, you should find any substance of fingerprints or biometrics. Then try to install the Lenovo Fingerprint Software.
